Question

GI−→

bisects ∠DGH
so that m∠DGI
is x−3
and m∠IGH
is 2x−13
. Find the value of x.

Answer 1

x = 10

Explanation:

since GI bisects ∠ DGH , that is divides it into 2 equal angles, then

∠ IGH = ∠ DGI , that is

2x - 13 = x - 3 ( subtract x from both sides )

x - 13 = - 3 ( add 13 to both sides )

x = 10
